[An analysis of 23 cases of early primary lung cancer].

This paper analyzed the clinical characteristics and long term therapeutic effectiveness of 23 cases of early primary lung cancer, which were coincide with diagnostic criteria of the disease in our country, and selected from among 1912 cases of primary bronchogenic carcinoma in our hospital during 1976-1986. The 5 year survival rate after operation was 72.8%. We compared the detection rates of the symptomatology and some principle methods of examination in wide use between early central and peripheral types of lung cancer. This paper emphasized that the diagnosis combined with multiple discipline was of importance to early finding the diseases. In this group, the comprehensive detection rate was 77.6%. To determine early central type of lung cancer depended in large part on hemoptysis, sputum cytology and fiberoptic bronchoscopy, and to find early peripheral type of lung cancer relied entirely on chest X-ray. Some other methods finding early lung cancer were also briefly discussed.
